bug 762304 - fakedata generation

fakedata.py is a module used by setupdb_app.py, used like so to populate a DB with synthetic test data:
```
setupdb_app.py --fakedata
```
Default is 15 days (may take a while to generate/load depending upon your system and connection), days are customizable:
```
setupdb_app.py --fakedata --fakedata_days=1
````
See ./scripts/integration-test.sh for an example of how this is used.
